[GRASS-dev] Re: python not launching in trunk

[Michael Barton]

Martin,

I am only receiving this error with wxGUI, not with any other wxPython  
applications. It also only happens AFTER the initial gis_setup.py  
screen (i.e., in wxPython and working fine) when it tries to start  
wx_gui.py.

Given my other problem mentioned earlier, I'm concerned that this is  
the result of an internal version check that is failing on the Mac  
even if correct version are installed.

Glynn may be right about a PYTHONPATH problem, but I do have an  
extensive, and AFAICT correct, PYTHONPATH on that computer. I may try  
to update GRASS and compile on my MacBook this weekend to see if it is  
something specific to my office computer or if it is something that  
changed in the GRASS source code.

Something interesting that William Kyngesbury just said that helps one  
issue I'm having. Apparently the startup app for GRASS compiled on a  
Mac ignores the .grass_bashrc file. This is not where my PYTHONPATH   
is located, but is where I was putting some environmental settings  
related to a Python issue on the MacBook--and they were not taking.
